题目:Max Points on a line Given n points on a 2D plane, find the maximum number of points that lie on the same straight line. 这道题需要稍微转变一下思路,用斜率来实现,试想找在同一条直线上的点,怎么判断在一条直线上,唯一的方式也只有斜率可以完成,我开始没想到,后来看网友的思路才想到的,下面是简单的实现:其中有一点小技巧,利用map<double, int>来存储具有相同斜率
直接用STL的的deque就好了... ---------------------------------------------------------------------- #include<cstdio> #include<algorithm> #include<cstring> #include<iostream> #include<deque> #define rep( i , n ) for( int i = 0 ; i &l
Given n points on a 2D plane, find the maximum number of points that lie on the same straight line. Example 1: Input: [[1,1],[2,2],[3,3]] Output: 3 Explanation: ^ | | o | o | o +-------------> 0 1 2 3 4 Example 2: Input: [[1,1],[3,2]
